A feasibility study to prepare a reference material of methyl mercury (MeHg) is reported. The dry sediment was tested with different solutions to understand how MeHg is bond to sediment matrix. For this we have tested the sediment with water, where a

One hundred six strains of aerobic bacteria were isolated from the Fiora River which drains an area of cinnabar deposits in southern Tuscany, Italy. Thirty-seven of the strains grew on an agar medium containing 10μg/ml Hg (as HgCl2) with all of thes

A method of detecting methylmercury species (MeHg) and dimethylmercury (DMM) has been studied. MeHg was transformed prior to its determination as methylmercury hydride (MMH) by use of NaBH4. The two volatile forms of organic mercury were detected by

A sensitive and specific technique, gas chromatography/Fourier transform infrared spectroscopy (GC/FTIR), has been used to detect traces of methane from the biodegradation of methylmercury due to the detoxification process of Pseudomonas putida strai

We report a novel aqueous derivatization of methylmercury chloride by NaBH 4 to mehtymercury hydride (CH 3 HgH), a volatile and unexpectedly stable species which we determined has a half-life of approximately 2 h. The analytical apparatus consisted o

Bacteria are resistant to Hg compounds by virtue of two specific enzymes: mercuric reductase and organomercurial lyase. We investigate these specific enzyme systems 1) to determine McHg in biological samples by its enzymatic transformation to the res

A new method is suggested for determining methylmercury in biological samples. The determination is based on the use of whole cells of a broad-spectrum mercury-resistant bacterium, Pseudomonas putida, strain FB1, which is induced to produce the enzym
